The Devel::SmallProf profiler is focused on the time taken for a program
run on a line-by-line basis. It is intended to be as "small" in terms
of impact on the speed and memory usage of the profiled program as
possible and also in terms of being simple to use.

Some OCD cleanups on some of the perl@ ports.
- Remove dependencies in core
- Put testing depends in TEST_DEPENDS
- Remove unnecessary bsd.port.options.mk inclusions
- Remove checks for Perl versions that no longer exist in the ports tree
- Sort plists, some of which were so jumbled that I have to assume
the plist was randomized before committing
A lot of the plist changes in this commit are moving PERL5_MAN3 after
SITE_PERL. It's repo churn now, but it makes updating the ports later
far easier.

Change the way Perl modules are installed, update the default Perl to 5.18.
Before, we had:
site_perl : lib/perl5/site_perl/5.18
site_perl/perl_arch : lib/perl5/site_perl/5.18/mach
perl_man3 : lib/perl5/5.18/man/man3
Now we have:
site_perl : lib/perl5/site_perl
site_arch : lib/perl5/site_perl/mach/5.18
perl_man3 : lib/perl5/site_perl/man/man3
Modules without any .so will be installed at the same place regardless of the
